The Lowdown
Alright folks, Rusty here. We’ve got a long, tough stretch ahead for this stretch of coast. The next 16 days are looking lean, real lean — no standout surf on the horizon. There’s a gap right from the start, with no proper recommendations, so let’s not pretend otherwise.
The first chance you’ll see anything surfable lands on Friday, July 31st at Kennebunk Beach. It’s a sheltered little nook that needs everything to line up. We’ve got a weak, 2ft swell sliding in from the SE with a 10-second period. The combined swell energy is a modest 127, so it’s low on grunt. But here’s the kicker: Friday morning the wind is dead calm — glassy as a mirror. That’s your window. For a couple of hours, you might find a clean, knee-high wave. The water temp is about average for this time of year, nothing wild. After that, the southerly breeze kicks in and the whole thing turns to mush by afternoon.
From there, it’s a grim slog. Saturday the 1st through to Saturday the 15th of August is one long, empty stretch of poor surf conditions. Swells stay tiny — mostly under 2ft — with short, weak periods and lousy cross-onshore or onshore wind. The combined energy readings all stay under 100, often below 50. That’s barely enough to surf a ripple. The crowds at Kennebunk Beach can pop up when it’s good, but that’s not the problem here — the problem is there’s nothing to surf.
If you’re a kiter, there are a few afternoons with a moderate southerly breeze and a bit of bump, but for a paddle surfer, it’s a write-off. The stretch from the 2nd to the 9th is particularly hopeless, just day after day of weak, wind-chopped slop.
Bottom line: the only half-decent chance you’ve got in this whole 16-day window is Friday, July 31st before the wind gets up. After that, you’re better off storing the wax and double-checking the forecast further out. Sometimes it stays poor like this; it’s a normal blank run for this area.
Stay patient,
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
